BACKGROUND: Propranolol has become the treatment of choice for infantile hemangiomas (IH). Neither the pathogenesis of IH nor the mechanism of action of propranolol on them are well understood. Possible explanations include the inhibition of angiogenesis by decreasing vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), induction of vascular endothelial cell apoptosis and vasoconstriction. OBJECTIVES: The aim of the study was to assess serum concentrations of VEGF and bFGF in the course of propranolol therapy of IH in children, and to assess their clinical implications...

BACKGROUND/OBJECTIVES: Efficacy of topical sirolimus has recently been described in lymphatic anomalies but not in other types of vascular anomalies. To our knowledge, systemic absorption of topical sirolimus in these lesions has not yet been reported. The objective was to evaluate the efficacy, tolerance, and absorption of topical sirolimus 0.1% with different types of vascular anomalies in children. METHODS: Sirolimus 0.1% was applied on cutaneous vascular anomalies in six children aged 2-17...

There was an outbreak of hemangioma associated with avian leukosis virus subgroup J (ALV-J) between 2006 and 2010 in China in commercial layer chickens. Recently, severe hemangiomas broke out in Hy-Line layer chickens on a poultry farm in 2017 where ALV was eradicated earlier. Six isolates of ALV-J, named SDAU1701-SDAU1706, were characterized by virus isolation and sequence analysis of the complete proviral genomes. Avian leukosis virus subgroup J was identified by an immunofluorescence assay with monoclonal antibody JE9, whereas Marek's disease virus or reticuloendotheliosis virus was not detected...

We present the case of a 15-year-old girl who presented with an unusual grouping of lesions on her upper left leg. The lesions had been present since birth. The patient had five different types of lesions: 1) transparent grouped or scattered yellowish vesicles; 2) keratotic-surfaced, grouped dark-yellowish papules; 3) bright-red grouped papules; 4) keratotic-surfaced grouped dark-red papules; and 5) patchy, punctate, and erythematous red macules. All of the lesions were intertwined along the lines of Blaschko and were in the form of irregular serpiginous plaques...

Background: Propranolol (PPN) is a therapeutic option for the treatment of infantile hemangiomas. This study aimed at the development of nanoemulsion (NE) containing 1% PPN, characterization of the system, and safety studies based on ex vivo permeation, cytotoxicity, and biodistribution in vivo. Methods: The formulation was developed and characterized in relation to the droplet size, polydispersity index (PDI), pH, zeta potential, and electronic microscopy. Ex vivo permeation studies were used to evaluate the cutaneous retention of PPN in the epidermis and dermis...

Spindle cell hemangioma (SCH) is a unique benign vascular lesion. We present a case of SCH in the upper lip of a 41-year-old woman. A submucosal nodular mass 30 × 20 mm in size was observed in the left upper lip. The mass developed 5 years earlier and enlarged after repeated ethanol injections. The mass was elastic firm, mobile, bluish in color, and well demarcated in magnetic resonance imaging. Under the clinical diagnosis of hemangioma, surgical excision was performed under local anesthesia. Microscopically, the lesion was composed of irregular cavernous spaces and multiple solid cellular areas...

Aggressive vertebral hemangiomas are rare tumors of the spine. The treatment management strategy usually consists of vertebroplasty, radiation therapy or in rare cases of surgical strategy. We present a case of a bulging sacral S1-S2 hemangioma in the spinal canal that could not be managed in the usual manner. Here, we demonstrate the usefulness of radiofrequency ablation technique as an alternative treatment as well as robotic assistance for optimal placement of the ablation probe within the lesion.

Due to significant improvements in morbidity and mortality, surgery with curative intent is now the standard of care for patients with colorectal liver metastases who are surgical candidates. As a result, highly accurate preoperative per-lesion diagnosis is crucial. However, in some instances, this remains limited with standard techniques, including magnetic resonance imaging (MRI) with conventional contrast agents. Delayed retention of contrast of fibrotic liver metastases on MRI with extracellular contrast agents may mimic the late retention of contrast in hemangiomas and represent a diagnostic pitfall that limits diagnosis...

PURPOSE: To describe the vascular changes of circumscribed choroidal hemangioma (CCH) after ruthenium-106 brachytherapy using optical coherence tomography angiography (angio-OCT). METHODS: Seven eyes of 7 patients diagnosed with symptomatic CCH who underwent ruthenium-106 plaque radiotherapy were included in the study. Patients underwent complete ophthalmic examination, bulbar echography and angio-OCT. The same protocol was applied 1 year after ruthenium-106 brachytherapy...

The use of propranolol for the treatment of infantile hemangioma (IH) has been widely investigated in recent years. However, the underlying therapeutic mechanism of propranolol for the treatment of IH remains poorly understood. The aim of the present study was to investigate the expression of proteins regulated by cellular tumor antigen p53 (p53) in associated apoptosis pathways in IH endothelial cells (HemECs) treated with propranolol. Furthermore, the present study aimed to investigate the exact apoptotic pathway underlying the therapeutic effect of propranolol against IH...

BACKGROUND/OBJECTIVES: Infantile hemangiomas are the most common benign tumors of childhood. Although some children with periocular infantile hemangiomas do not require treatment, these lesions may result in amblyopia and visual impairment if not properly treated. We have attempted to characterize clinical features of periocular infantile hemangiomas that predict negative ocular outcomes and thus require prompt referral to an ophthalmologist and initiation of therapy. METHODS: This study included children with periocular infantile hemangiomas consecutively seen at Ann & Robert H...

BACKGROUND: We investigated two cases of deceptively bland cutaneous angiosarcoma, which showed a uniform clinical presentation with a rapidly growing tumor on the nose. It remains unclear whether this was a primary cutaneous manifestation or a metastasis. Both tumors initially presented a high histologic overlap with a benign vascular tumor. The diagnosis was primarily based on the rapidly progressing clinical course and on the results of the staging procedures. METHODS: Immunohistochemical stains were performed for cytokeratin (AE1/AE3 and MNF116), CD31, ERG, CD34(HPCA1/my10), D2-40/podoplanin, LYVE-1, Ki67, PHH3, αSMA(1A4), MYC, FOS-B, CAMTA-1, TFE-3, WT1, nestin, VEGFR-2(KDR), VEGFR-3(FLT4), HHV8...

Background  Surgical removal of parapharyngeal space tumors (PPST) poses challenges due to the complex anatomy of the region. PPSTs are routinely resected by a transcervical approach using blind finger dissection. Large PPSTs or those located high at the skull base, often require transmandibular or infratemporal fossa approaches, associated with considerable morbidity. Objective  Here, we describe an approach for PPST removal that comprises transcervical endoscopic, with or without transoral robotic technique...

AIM: Presentation of the efficacy of infrared laser for the treatment of retinal capillary hemangioma (RCH). METHODS: The treatment and follow-up of nine eyes (fourteen tumors of different sizes and localizations) in seven patients (five children) with RCH. Infrared diode laser (810 nm) was used for modified transpupillary thermotherapy (TTT) in long exposition mode and power between 200 and 1200 mW with a beam diameter of 2 mm (indirect ophthalmoscope, +28 D or +40 D lens) or 0...

Pyogenic granuloma, also called lobular capillary hemangioma, is a benign vascular lesion of the skin and mucous membranes. While the majority of pyogenic granulomas in the oral cavity involve the gingiva, they also infrequently present at other sites including lips, oral mucosa, palate, and tongue. We report a case of a pyogenic granuloma of the tongue in a five-year old female patient.

Purpose: To describe the clinical course of a patient with a retrobulbar orbital tumor causing myopic shift and macular pucker. Observation: Following complete surgical removal of a retrobulbar orbital cavernous hemangioma, the myopic shift improved but the macular pucker persisted even 3 years after orbital surgery, with no sign of tumor recurrence. Conclusion and importance: Chorioretinal folds secondary to chronic mechanical force from an orbital tumor may persist long after the tumor is removed...
